Kosmotropes are stabilizing solutes which increase the order of water (such as polyhydric alcohols [ 307 ], trehalose, trimethylamine N -oxide, glycine betaine, ectoine, proline and various other zwitterions) whereas chaotropes create weaker hydrogen bonding, decreasing the order of water, increasing its surface tension and destabilizing macromolecular structures (such as guanidinium chloride and urea at high concentrations).

这是稳定增长kosmotropes溶质水秩序(如多元醇〔307〕、海藻糖、甲胺氮氧化物、甜菜碱、ectoine，脯氨酸和其他各种盐)而创造chaotropes氢键较弱，为了减少用水，增加其表面张力和大分子结构不稳定。
